You would be very lucky if they bolted right in. You can switch from standard seats to the recarro type, at least I did in my 88 325... but if the seats are for sale, they should know what they will fit, or.... you can find out by measuring them. you want to X the measurements between the seat bolts, then measure across from front left to right, then the rear. Also measure front to rear on left and right.
Good luck
